Goal: To measure what people consider an effective treatment for acne, 145 people with acne (PwA) took part, 897 answered the treatment was effective, and 742 fitted with possible outcomes:

-More than a third said that there were fewer spots.-A fifth said it was less redness.-Around one in seven said it was a reduction in spot size and around the same proportion said it was a reduction in pain/discomfort.

How did patients observe changes ?-Looking at the skin was the most widely adopted way of assessing (16.3% of people) and Visual Signs were most considered. Symptoms were less used.Quality of life was only infrequently mentioned

Comments: 1.objective measurements run in trials (lesion counts, severity) do not include measurements done by patients at a single point in time, which can include psychosocial well-being and mood. Further studies will need to take this into account.2. The authors use the term “People with Acne (PwA)” as Acne affects not only patients; many manage themselves and never see a doctor.

Study from UK, a quarter of those who responded lived outside of the UK
